SCREEN -DOOR SPRING-HINGE.

Specification of Letters Patent.

Patented Oct. 6, 1908.

Application filed. January 15, 1908. Serial No. 410,893.

To all whom it may concern:

Be it known that I, ALBERT FALKENRATH, a citizen of the United States,residing at Racine, in the county of Racine and State of WVisconsin,have invented a new and useful Surface or Screen-Door Spring-Hinge, ofwhich the following is a specification.

My invention relates to certain new and useful improvements in hinges,and the object of my invention is to produce a hinge which is simple inconstruction, not liable to break or get out of repair, cheap toconstruct and durable.

With these and other objects in view my invention consists in certainconstructions, combinations and arrangements of parts one form of whichwill be illustrated in the accompanying drawings and then the inventionparticularly pointed out in the appended claims.

Referring to the drawings wherein I show one form of my invention andwherein the same reference character denotes the same part in theseveral views, Figure 1 is a perspective view of a hinge constructed inaccordance with my invention; Fig. 2 is a sectional view taken on line2, 2 of Fig. 1; Fig. 3 is a perspective view of the outer leaf of thehinge; Fig. 4 is a horizontal section on line 4, 4 of Fig. 1, and Fig. 5a horizontal section on line 5, 5 of Fig. 3.

1, 1, designate the side leaves of the hinge which are suitablyperforated at 2 to receive screws or other securing means. The leavesare provided at their adjacent ends with the ears 3, 3, bent at rightangles to the body of the leaves and are perforated at 3 to receive thepintle 4.

The ears on one of the leaves are bent outwardly and form cup-shapedseats or bearings in which are seated the ears of the other leaf of thehinge. This bearing serves as an additional means to hold the leaves inproper working relation one with the other and prevents lateral play ofthe parts due to wear thereof. 5 are washers placed between the heads toreduce wear and friction.

Extending between the ears 3 is a barrel 6 and secured in one end ofthis barrel is the plug 7 which has the central projection 8 slotted at9 to receive the inwardly bent end 10 of the spiral spring 11. The plugis centrally bored at 12 through which the pintle 4 passes. The outerend of the plug is flush with the end of the barrel (3, so that it formsa bearing against the adjacent ear 3 when the parts are in position, theplug being held in this position in the barrel by a pin 13 passingthrough the barrel into the plug. The other end of the barrel 6 isclosed by plug 14, which rotatably fits the end of the barrel and on theouter end of the plug I form an enlarged head 15 which preferably has adiameter equal to the diameter of the barrel 6 and in its periphery isprovided with the radial perforations 16 into which the pin 17 may beplaced to hold the hinge under tension as will be hereinafter described.

On the inner end of the head 14 is formed the projection 18 slotted at19 to receive the inwardly bent end 20 of the spring 11. The plug 14 iscentrally bored at 21 through which the pintle 4 extends.

In assembling the parts the plug 7 is permanently secured in the barrelby driving the pin 13 through the opening in the barrel into the openingin the head 7 whereby the head is fastened into the barrel with itsouter end flush with the end of the barrel and its central projection 8extending into the barrel. The pin 13 projects out from the side of thebarrel and forms a stop adapted to engage one of the leaves. The spring11 is now slipped into the barrel and one of the inwardly bent endscaused to engage the slot 9 which permits the spring to pass down overthe projection 8 and whereby the spring is rigidly secured to thebarrel. If desired grease can now be placed in the barrel to insure easyworking and then the plug 14 slipped into the open end of the barrel,the end 20 of the spring having been first caused to engage the slot 19in the projection 18. When the plug 14 has been pressed into the barrelso that the head 15 contacts with the end of the barrel, the barrel withits heads in position can now be placed between the ears 3 of the leaves1, and the pintle passed through the openings which are now in line andthe head 22 of the pintle secured thereto. A tool can now be inserted inone of the openings 16 and as soon as the pin 13 is in contact with oneof the leaves further rotation of the plug 14 will put the spring undertension, and when the tension on the spring is suflicient the pin 17 canbe inserted and upon removing the tool from the opening 16 the pin 17will be forced against the other leaf, consequently tending to hold theleaves in the position shown in Fig. 1.

Vhile I have described my invention in connection with a surface hinge,it is to be understood that my invention is equally applicable to a jambhinge or a double acting one, and that many changes may be made in theform, construction and arrangements of parts without departing from thespirit of my invention.

hat I claim as new and desire to secure by Letters Patent is In aspring-hinge, the combination with a pair of leaves bent at their upperand lower edges to form pintle receiving ears, the ears on one of theleaves being bent outwardly to form a cup-shaped seat or bearing for theairs of the other leaf, and washers seated on I said pintle between therespective bearing portions of the leaves, of a barrel confined betweenthe ears of the shorter leaf, rotatable, slotted and perforated headsclosing the ends of said barrel, a spring therein having its ends seatedin said heads a pintle threaded through the leaf ears and the barrelheads, pins seated in the perforations of the h ads to prevent therotation thereof, and a pin adapted to be inserted in the perforation inthe head to rotate the same to tighten the spring, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two witnesses.
